Failed to connect to development server using “adb reverse”

Question

I'm running a react-native app with an android emulator running normal, but when I use the command "react-native run-android" that launch me this error:

warn Failed to connect to development server using "adb reverse": spawnSync C:\Users\HP-Envy\AppData\Local\Android\Sdk;/platform-tools/adb ENOENT

Is the packager running? You can also start it up by itself using react-native start. May be the packager is not starting up at all. — Nooruddin Lakhani

Please try this:

$ adb reconnect

This is not necessary in most cases, but just in case, let's reset your connection with your mobile and restart adb server. Finally:

$ adb reverse tcp:8081 tcp:8081

So, whenever your mobile device tries to access any port 8081 on itself it will be routed to the 8081 port on your PC.
